031-503-3004 (SL2) - Supervise the Crossing of a Contaminated Area

Standards: Supervised a unit crossing or passing through a nuclear, biological, or chemical contaminated area without producing additional casualties or spreading contamination.

Conditions:
You receive orders to cross a nuclear,
biological, or chemical contaminated area.
Given a unit with mission-oriented
protection posture (MOPP) gear; organic
decontamination equipment (such as M13
decontaminating apparatus portable (DAP) and
individual decontaminating kits), chemical
(such as M256 chemical agent detector kit,
M8 chemical agent detector paper, and M9
chemical detector tape) and radiological
(such as IM174-series radiation, detection,
indication, and computation [RADIAC] meter,
AN/UDR-13 and AN/VDR-2 RADIAC sets, and IM93
dosimeter) detection and/or warning devices;
shielding material (such as sandbags); and a
defined NBC contaminated area.

Standards:
Supervised a unit crossing or passing
through a nuclear, biological, or chemical
contaminated area without producing
additional casualties or spreading
contamination.

Performance
Steps

1.   Supervise a unit crossing a nuclear contaminated
area.

a.
Before crossing-

(1) 
Provide shielding for
personnel. Use vehicles if
possible. Place sandbags on the
floor and sides of all vehicles
(within reason for nonarmored
vehicles).

(2) 
Tell vehicle operators
to close all doors, windows,
hatches, and vents on their
vehicles.

(3) 
Have soldiers cover all
exposed skin by rolling down their
sleeves and buttoning their
collars. Ensure that they wear
handkerchiefs or similar cloths
over their noses and mouths to
keep from breathing radioactive
dirt or dust.

(4) 
Select the shortest
possible route that would cause
the least contamination and permit
the fastest travel based on
mission, enemy, terrain, troops,
time available, and civilian
considerations (METT-TC).

(5) 
Ensure that IM93
dosimeters are available and
charged to zero.

(6) 
Ensure that AN/UDR-13
and AN/VDR-2 RADIAC sets are
available and operational.

(7) 
Delay entry into the
area as long as possible within
the limits of the mission.

b.
During crossing-

(1) 
Perform continuous
monitoring.

(2) 
Have the monitors watch
the dose rate on the AN/UDR-13 or
AN/VDR-2 RADIAC set. Instruct them
to keep you informed. Ensure that
the commander’s turn-back dose
rate is not exceeded without
approval.

(3) 
Have all personnel with
dosimeters check them often to
ensure that the commander’s
turn-back dose is not exceeded
without approval.

(4) 
Move through the area
as quickly as possible. Do not
forget safety or security.

(5) 
Ensure that vehicles
are far enough apart during
movement to minimize dust.
Consider the tactical situation,
the command, and the control when
spacing the vehicles.

c. After crossing-

(1) 
Have personnel check
themselves and their equipment for
contamination. Have everyone brush
the dust from his or her clothing.

(2) 
Determine if
decontamination is required.

2.   Supervise a unit crossing a chemical contaminated
area.

a.
Before crossing-

(1) 
Select the shortest
possible route that would cause
the least contamination and allow
the fastest travel based on
METT-TC.

(2) 
Tell vehicle operators
to close all doors, windows,
hatches, and vents on their
vehicles.

(3) 
Assume MOPP 4.

(4) 
Have soldiers attach M9
detector paper to their clothing
and equipment.

b.
During crossing-

(1) 
Ensure that vehicles
are far enough apart during
movement to minimize dust.
Consider the tactical situation,
the command, and the control when
spacing vehicles.

(2) 
Move through the area
as quickly as possible. Do not
forget safety or security.
Continuously monitor personnel for
chemical agent symptoms, and give
first aid as required.

(3) 
Ensure that soldiers
avoid touching anything in the
area if possible.

(4) 
Monitor personnel
closely for symptoms of heat
stress, and minimize excessive
heat buildup.

c.
After crossing-

(1) 
Continue to monitor
soldiers for chemical agent
symptoms, and give first aid as
required.

(2) 
Have soldiers use
detector paper to check themselves
and their equipment for
contamination.

(3) 
Have soldiers use their
decontaminating kits to
decontaminate any contaminated
skin or personal equipment. Seek
medical aid as required.

(4) 
Have vehicle operators
use available decontaminating
equipment to decontaminate their
vehicles, if required.

3.   Supervise a unit crossing a biological contaminated
area.

a. Before crossing-

(1)  Select the shortest
possible route that would cause
the least contamination and allow
the fastest travel based on
METT-TC.

(2) 
Tell vehicle operators
to close all doors, windows,
hatches, and vents on their
vehicles.

(3) 
Assume the appropriate
MOPP level, as required.

b.
During crossing-

(1) 
Move through the area
as quickly as possible. Do NOT
forget safety or security.

(2) 
Ensure that personnel
do NOT touch anything in the area
that can be avoided.

(3) 
Ensure that vehicles
are far enough apart during
movement to minimize dust. 
Consider the tactical
situation, the command, and the
control when spacing vehicles.

c.
After crossing-

(1) 
Decontaminate personnel
and equipment by washing them
thoroughly with hot, soapy water,
if time and mission permit.

(2) 
Do as many of the steps
as possible for the types of
contamination present in the area.

(3) 
Seek medical aid if
required.

Evaluation
Preparation:

Setup:
Evaluate this task during a field exercise
or a normal training session. The
contaminated area may have been marked with
the appropriate markers, or a diagram may
have been prepared showing the boundary of
the contaminated area, the soldier’s present
location, and the desired direction of
travel. Gather the necessary equipment and
personnel to conduct the movement. Obtain,
for training purposes, fictitious
commander’s operational exposure guidance (OEG)
on the turn-back dose and the turn-back dose
rate.

Note.
Before conducting this task, ensure that
soldiers have been trained on the following
tasks: 031-503-2020, 031-503-2001,
031-503-2013, 031-503-1037, 031-503-1013,
and 031-503-2023.

Brief
Soldier:
Tell the soldier to supervise
the movement of a unit through a nuclear,
biologically, or chemically contaminated
area by performing the appropriate measures
before, during, and after the movement
through the area. Give the soldier an
illustration, showing the boundary of the
contaminated area, the soldier’s present
location, and desired direction of travel
through the contaminated area.

Performance
Measures

GO

NO
GO

1.   Supervised a unit crossing a nuclear contaminated
area.





2.   Supervised a unit crossing a chemically
contaminated area.





3.   Supervised a unit crossing a biologically
contaminated area.





Evaluation
Guidance:
Score the soldier GO if all
performance measures are passed. Score the
soldier NO GO if any performance measure is
failed. If the soldier fails, show him how
to do it correctly.
